METHOD AND MEANS FOR Application filed March. 1,

In the process of removing brasses from car journal s, it is customary to place a ack under the journal box and lift the; box free of the axle to an extent sufficient to allow the brass 'to'be pulled up over the collar on the end of the axle and to be removed from the box. In this operation, the weight ofthe car is thrown more upon the other end of the axle, thereby tending to lift the wheel near which the brass is to be removed. This would consequently raise the axle with the bearing so that the axle does not readily separate from the bearing to permit-the removal of the latter. p

The object of my invention is to provide means and a method for overcoming this difiiculty. The invention comprises a clamping device adapted to be applied so as to hold the wheel to the rail, and to this end it has upper and lower jaws for fitting respectively over the outer rim of the wheel and under the head or top of the rail. It

further comprises an adjustable feature whereby such clamping device can be made to accommodate wheels andrails having various thicknesses of rims and heads respectively. It further comprises a method of applying such clamps so that they will be held in place by the jack itself, to prevent them from slipping oifzthe inclined faces of V the wheel rim and rail head. It further provides means attachable to the-clamps for thus utilizing the jack as an abutment to hold the clamps tight against the rim and rail. r

In the accompanying drawing:

Figure 2 is a transverse section through the ournal box.

Figure 3 is a view on an enlarged-scale of one form of clamp.'

Figure 4.- is a view of another form of clamp.

InFigure 1 1 indicates across tie, 2 a railway rail, 3 a railway car wheelfll: the axle for the same, and 5 a journal'box. At (3 is shown a jack adapted to .rest on the tie l and be brought to bear under the bottom of the journal box 5. To hold thewheel 3 down when the jack is applied, I provide a clamp 9 having two jaws, one adapted to fit over the inner periphery of the wheel rim and the other adapted to fit under the head .sition against the lifting REMOVING. can BRAss s.

of the rail. As both the rims of the wheel having protuberances13 adapted to fit in the recesses of'the first-mentioned clamp. A thumb screw 14 orbolt, or other means such as a clamping ring 15, may be used to hold .the two parts of the clamp together.

It will be seen that by loosening the screw,

one member may be slid along the other until the protuberances 13 match the proper holes 11 to'make' the distances between the ends of the clamps fit the particular rail and wheel to which theyare to be applied. In Figure 4(the same object is accomplished by of malleable iron or cast steel, witha matching member 17 adapted to pass through the same and be held in its proper position by vmeans of a hollow clamp member 16 made means of a key passed through slots 18 in p the two members, one or both members having a plurality of slots to provide for the requisite adjustment. At the back of the clamp, I prefer to attach abrace 19 of proper dimensionsto occupy the space between the jack and the clamp, to hold the clamp firmly up against the inclined faces of the wheelrim and. rail head. lVit-h this precaution, the clamp is not liable, when the strain is applied, to slide off these inclined faces.

Vhile I have shown a particular embodiment of my invention, it will be understood that in its general features the invention will 7 cover many other forms.

I claim I 1. A clamp for clampinga" car wheel to the rail when the car is lifted by a jack, said clamp having curved jaws for engaging the wheel rim and the underside of the rail head anda curved brace permitting the clamp to f rest in engaging position against the lifting ack irrespective of the contour of the latter.
